Answer:

A. (3, -2)

Step-by-step explanation:

A 180° rotation about the origin places an object in the quadrant diagonal to the one it started in.  Moving the object two 90° turns, will place it in a coordinate that will make the values of 'x' and 'y' opposite to the initial value.  In this case, vertex A has an initial point of (-3, 2), so after a 180° rotation, it would be (3, -2).
